ABSTRACT:
A vehicle having a man power driving system in which a driving force by man power is applied through a gear change mechanism to rotate a wheel, an a motor driving system in which the wheel is rotated by a driving force of a motor. The man power driving system is equipped with a torque detector for detecting a man power driving force so as to drive the motor according to a magnitude of the man power driving force detected by the turque detector. A particularly durable gear change mechanism is not required, and thus a common gear change mechanism for bicycle can be used, thereby simplifying construction.
